Research Abstract |
We have previously identified clathrin heavy chain as a p53-binding protein. In this study, CHC is present in nuclei and promotes p53 transactivation through the enhancement of the interaction between p53 and p300, histone acetyltransferase. We also identified nuclear mitotic apparatus (NuMA)as a nuclear CHC-binding factor and showed that NuMA was a critical determinant for p53-transcriptional selectivity mediated by Cdk8. Moreover, the structural model of CHC-p53 interaction was constructed and an amino acid residue in CHC, which is important for p53 transactivation, was identified. Plasma membrane-associated p53 is involved in the regulation of CHC-dependent endocytosis and actin-mediated cell motility.
